Member Typedef Documentation
template<class T, class V, class R = V&, class D = std::ptrdiff_t>
typedef T Dune::RandomAccessIteratorFacade< T, V, R, D >::DerivedType |
The type of derived iterator.
The iterator has to define following functions have to be present:
// Access the value referred to. Reference dereference() const;
// Compare for equality with j equals(i);
// position the iterator at the next element. void increment()
// position the iterator at the previous element. void decrement()
// advance the iterator by a number of positions- void advance(DifferenceType n); // calculate the distance to another iterator. // One should incorporate an assertion wether // the same containers are referenced DifferenceType distanceTo(j) const;

Reference Dune::RandomAccessIteratorFacade< T, V, R, D >::operator[] | ( | DifferenceType | n | ) | const [inline] |
Get the element n positions from the current one.
- Parameters:
-
n The distance to the element.
- Returns:
- The element at that distance.
